PCA is managed by a full-duplex serial interface. A typical data frame is defined bya burst of 8 DCLK pulses followed by an assertion of a DLOAD pulse (these lines are driven by the host printing system.). During each frame, 32 bits of control or pri...
Hi, I'm using the STM32L451VETx and I'm configuring the ADC to read from the internal temperature sensor however the readings are lower than expected. Typical readings at around 21 degrees Celsius are only 3 degrees Celsius. I can see some change in ...
Hello There,I'm working on OTA application and successfully executed single bank OTA.Now I'm looking to switch to Dual bank operation to make it more reliable. So, there are 2 banks (memory areas) and after each update, the active bank changes. Means...
Hi,In our application we are using a cooling system(i.e., a FAN/DC motor). For which I have implemented TIM1 in PWM mode to control the speed of the FAN, the story doesn't end here. The FAN provides a feedback which is called as pulse sensor which ca...
LORA DATASHEETThe default settings for the UART interface are 57600 bps, 8 bits, no parity, 1 Stop bit,no flow control. The baud rate can be changed by triggering the auto-baud detectionsequence of the module. To do this, the host system needs to tra...
Hello.I have been working on a project where the I2C based sensor I have chosen works by itself. When I enable a SPI based module, the I2C sensor does not seem to send any data.The I2C lines don't even have any conflicts with other pins.I have includ...
I order the X-NUCLEO-OUT02A1 and I work with a NUCLEO-F746ZG.These two boards aren't directly compatible I know.But they communicate with SPI, so I'm sure that you just can implement the communication with a bit of mapping with some breadboard wires....
STM32H7 SPI DMA not workingHi. I have stm32H745 nucleo board, in my project i want send data from MOSI via DMA (i did the same on old F4 discovery correctly).PE_14, SPI4 , DMA2_stream3, DMUX11=84 (for tx spi4)In project i need to send data (fb[][]) t...
I wanted to know which channel is converted latest. I configured as belowhadc1.Instance = ADC1; hadc1.Init.ClockPrescaler = ADC_CLOCK_SYNC_PCLK_DIV2; hadc1.Init.Resolution = ADC_RESOLUTION_12B; hadc1.Init.DataAlign = ADC_DATAALIGN_RIGHT; hadc...
